In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1080026-94-3, name is Ethyl 4,5,6,7-tetrahydrothieno[3,2-c]pyridine-2-carboxylate, the common compound, a new synthetic route is introduced below. COA of Formula: C10H13NO2S
615 mg (987 mumol, 50% purity) 5-tert.-butyl-2-ethyl 6,7-dihydro-4H-thieno[3,2-c]pyridine-2,5-dicarboxylate are dissolved in 4 ml of a mixture of TFA and DCM (v/v 1:1) and stirred for 30 minutes at RT. The reaction mixture is neutralised by the addition of TEA and evaporated down i. vac.The crude product thus obtained is dissolved in 4 ml formic acid and combined with 0.5 ml (6.7 mmol) formalin solution (37% in water). The reaction mixture is stirred for 16 hours at 70 C. After cooling to RT the mixture is made basic with 50% aqueous sodium hydroxide solution and saturated sodium hydrogen carbonate solution and extracted with ethyl acetate. The organic phase is washed three times with water, dried on sodium sulphate, filtered and evaporated down i. vac. The residue is purified by RP-HPLC.Rt value: 0.90 min (Method B)C11H15NO2S×CF3CO2H (225.31)Mass spectrum: (M+H)+=226
The synthetic route of 1080026-94-3 has been constantly updated, and we look forward to future research findings.
